Sanicula gregaria, Bicknell. This species was collected in New 
Hampshire on the wooded banks of the Connecticut River, at Wal- 
pole on August 2, 1899, by Mr. M. L. Fernald. I have seen his 
specimens in the Gray Herbarium, and a cross should represent this 
in my list. 
Sanicula trifoliata, Bicknell. This species was collected at Man- 
chester, Maine, by Prof. F. Lamson-Scribner as early as 1873. A 
specimen is in the New England Botanical Club Herbarium where 
I have examined it. It has also been taken at Alstead, New Hamp- 
shire, by Mr. Fernald in 1899. I have seen a specimen from this 
locality and the two States should each be represented by a cross in 
my list. 
Sium Carsonii, Durand. The more I see of this plant the more I 
am convinced that it is only an aquatic variety or mere form or state 
of cicufaefoliwm. The peculiar nondescript character of the leaves 
and entire plant in its extreme immersed form tends to this conclu- 
sion, and I have in my herbarium a series of specimens showing a 
complete gradation from the typical cécutaefolium to the typical 
Carson. ‘The immersed form fruits much less frequently and, as is 
natural, the fruit is somewhat reduced but its size seems to depend 
upon the degree of immersion of the plant. The amount of variation 
in the shape of the leaves from cicwfacfolium also depends upon the 
degree of immersion, and it all tends to show, to my mind, that 
Carsonti has been evolved from cicutaefolium and is certainly no 
more than a variety of it, as intermediate forms exist in abundance to 
show this connection. 
Taenidia integerrima, Drude. This name should take the place of 
Pimpinella integerrima, Gray. Our native species has proved, 
according to the opinion of recent monographers, to be generically 
distinct from the old world Pimpinella. 
Thaspium aureum, Nutt. (Thaspium trifoliatum aureum Britton). 
This species is credited to New England in the Monograph of the 
North American Umbelliferae, Coulter and Rose, Washington, 1900, 
p. 146, and to Rhode Island in Britton and Brown’s Illustrated Flora, 
IL, 1897, p. 518. Professor Coulter, Dr. Rose and Dr. Britton have 
kindly furnished me with information as to their authority for these 
statements. The reference to New England is either a mistake or it 
was based on tradition, and was made from previous records, as no 
specimens from New England have ever been seen by the authors of
